> When we replay recovered edits, we used the minSeqId of Store, It may cause 
> deleted data appeared again.
> Let's see how it happens. Suppose the region with two families(cf1,cf2)
> 1.put one data to the region (put r1,cf1:q1,v1)
> 2.move the region from server A to server B.
> 3.delete the data put by step 1(delete r1)
> 4.flush this region.
> 5.make major compaction for this region
> 6.move the region from server B to server A.
> 7.Abort server A
> 8.After the region is online, we could get the deleted data(r1,cf1:q1,v1)
> (When we replay recovered edits, we used the minSeqId of Store, because cf2 
> has no store files, so its seqId is 0, so the edit log of put data will be 
> replayed to the region)
